BACKGROUND OF THE PRESENT INVENTION

1. Field of Invention

The present invention relates to sportsboard, and more particularly to asportsboard comprising a locking arrangement which is capable ofsecurely and conveniently locking the sportsboard onto a fixture so asto avoid being stolen.

2. Description of Related Arts

Conventional sportsboard, such as a surfboard, are widely utilized bythose who love water sports including the likes of surfing, wake riding,snowboarding, kayaking, and skating. A conventional sportsboard usuallycomprises a riding board having a predetermined shape which is adaptedto fit a predetermined water sports, and a stabilizing device, such as afin, extended from the riding board for steering, propelling andstabilizing of the sportsboard when it is gliding on a water surface.

Conventional sportsboard has a pressing disadvantage of lacking aneffective locking device for locking the sportsboard when it is not inuse in order to prevent such undesirable conduct as theft. Theunderlying difficulty in designing such a locking device lies with itsinterference with the normal operation of the spbrtsboard. Specifically,any add on locking device is liable to deteriorate the performance ofthe sportsboard. This perhaps small and insignificant deterioration inperformance may become material when it is to be utilized inprofessional competition in which extremely accurate assessment ofperformance is required. Thus, a small deterioration in performance mayresult in material alteration in the ranking in a particular watersports competition.

Obviously, the deterioration in performance is not necessarily materialwhen the sportsboard is utilized only for entertainment purpose.However, it doesn't mean that it poses no problem when the add-onlocking device, such as a locking hole drilled on the riding board,affects the stability of the whole sportsboard. As such, it is evenunsafe that the sportsboard is to be utilized for water sports.

Even though the locking device does not affect the general stability ofthe sportsboard, it may present a danger to the user during the courseof the water sports. For example, during surfing, the user mayunexpectedly encounter an intensely strong wave which brings the userout of the riding board. Normally, the user should be able to swim andgrab the riding board so as not to get lost of floating support in thewater. However, it is possible that the locking device, due to randommotion driven by the strong wave, accidentally hit the user, then, theuser may no longer be able to grab the sportsboard tightly and thenregain control thereof. In other words, the locking device may pose adanger to the user.

Since the sportsboard is fairly expensive, it is necessary to protect itfrom being stolen, especially when it is not in use. However, with theabove-mentioned problems, conventional locking device seems to providethe locking function at the expense of the quality of performance, whichis definitely undesirable. This presents a rather paradoxical dilemma inwhich two conflicting considerations equally prevail. In view of this, anovel sportsboard with a locking arrangement which is capable ofovercoming the above-mentioned difficulties has to be developed.
